- IMPROVEMENT IN CAR-COUPLING.

The Schedule referred to in these Letters Patent and making part of the same I, CHARLES M. HOAG, of Nassau, in the county of Rensselaer and State of New York, have invented certain Improvements in Self-acting Oar-Couplings, of which the following is a specification.

Nature and Objects of the Invention.

My inventlon relates to a combination of devices for the coupling of cars, so arranged that the operations of uncoupling and setting the apparatus for coupling the cars may be etfected from the platform or roof ot' the car, and the coupling of the cars etfected by running them in contact with each other, the objects of -my invention being to insure a certain and simple General Description.

A is the draw-bar, only differing from those in common use from having the opening in the head made with flaring sides, as shown at a a, and in such other slight changes as are required to adapt it to the proper working of the parts.

-B is the coupling-bolt, which moves vertically through the slots 0 l.) D, they being made of sufficient length to admit of a slight motion in the direction of the length of the draw-bar.

The coupling-bolt is made with two limbs, one of which, 1), passes through and secures the link J when the cars are coupled.

The other limb is provided with a notch, b, for securing the coupling-bolt in its proper position when drawn up.

E is asliding bolt bearing against the back of the coupling-bolt.

It works in the guides e e, and is kept in contact with the coupling-bolt by the spring Gr, which is placed between it and the stop F.

H is a spring fastened to the top side of the drawbar, and bearing on the shoulder of the coupling-bolt,

for the purpose of forcing it into its position in the operation of coupling.

I is a rod or chain, attached to the coupling-bolt for the purpose of drawing it out of the link. The other end of this rod may be carried to the roof, platform, or other place of safety on the car.

J is a link, commonly used for such purposes.

In couplingthe cars together, the coupling-bolt B, when drawn up, as shown in fig. 1, has its notch b forced on and secured to the front end of the slot .D, by means of the sliding bolt E and spring G, and is there held in proper position for e lfecting the coupling. The linkJ having been previously secured to the draw-bar of one of the cars to be coupled, is left projecting therefrom.

When motion is given to the car, the link J, upon striking againsteither of the flaring sides a a of the draw-bar A, is guided into the opening, where it strikes against the long limb of the coupling-bolt B, releasing the notch b, whereupon the spring H forces down the coupling-bolt B, whose limb I), entering the end of the link J, secures it, and the coupling is effected.

The spring G, in addition to the function already described, serves as an aid tothe bumper-spring commonly used behind the draw-bar.

The spring H, bearing upon the shoulder of the coupling-bolt B, as shown, causes a more instantaneous action of the coupling-bolt than can be obtained by gravity alone, thereby avoiding the liability of failme to connect caused by a recoil of the cars when The action of the spring H ppon the coupling-bolt B also keeps the link J in brought violently together.

a horizontal position, so as-to secure its proper en trance into the opening of the draw-bar of the adjoin ing car during the operation of coupling.

Claims.

I claim as my inventio1 1 1. The coupling-bolt B, constructed as shown and described, in combination with the spring H, for the purposes herein specified.

2. The combination of the draw-bar A, ooupling-
